The demand for organic products increased importantly over the last decennary . Hishtil , one of the conduce producers of constituent rooted\unrooted cutting of herb , has get a line this trend developing as they are involved in it from wampum . They get going to grow a selection of their assortment organically 10 to 15 year ago and now , they have intimately all their mixed bag , admit lavender , also available as an organically develop merchandise . As more and more growers all over the Earth are appear into the selection of constitutional refinement , Hishtil started to spread the noesis and experience they gain at their greenhouse in Israel .
need for organicAccording to Ephraim Weil , Agronomist , Plant Protection Specialist at Hishtil , the need for constitutive cuttings and new industrial plant increase in many rural area . " In recent years , we are seeing that a mount number of grower are look for organically grown flora , this as a outcome of , on the one hand , that progressively more type of pesticide are not allowed anymore and that the social pressure to circumscribe the use of goods and services of pesticide is rising in more and more res publica . "
Spreading the knowledgeSince the very beginning , so for over 40 years now , Hishtil has been in close impinging with their growers and spreading and sharing their knowledge and experience about grow their products . Also for constituent refinement , they are thirstily sharing it with their growers all over the world , which enable growers to better succeed . " Initially , we only had 10 crops that we also rise organic , now we have about 20 to 30 crops . ” Hishtil has a lot of nurseries all over the cosmos grow their products . “ It is great to see that in some countries like Mexico and South Africa , where constitutive polish is still quite young , it is being picked up rapidly , not only by the agriculturalist , but also by the industriousness in cosmopolitan . "
nail with pestsSo , how to cope with pest ? Below , and also published earlier inthis article on IsraelAgri , Weil explains .
" The main conventional method to grapple with pests is chemical spraying , but over the last few decades and particularly in late years , there have been more and more reasons to deoxidize chemical control and shift to environment friendly methods . Environmental contamination , employee safety equipment , peril for pollinators , rigid regularization regarding the role of chemicals , and the amount of pesticide residues permitted in consumable products , entire groups of very effective chemicals that have been banish – all of these have go to prepare an alternative way to control pests , " integrated pest management " ( IPM ) .
IPM means pest direction in a way that minimise the use of chemicals and emphasizes natural and dispirited - toxicity methods like pest caparison , low - endangerment pesticide , and other practices . The primary component part in IPM is biological control that is defined as the reduction of pest population by the use of natural enemies that in this circumstance are also called " beneficials " .
Predatory jot Phytoseiulus persimilis . " We would like to acknowledge Bio - Bee Biological Systems the IPM company we work with for their routine help and for the picture in this article . "
There are different kinds of enemies who have different strategy of attacking their prey . Two primary strategies are those of predators and parasitoids . vulture are species that feed directly on their prey and by doing so defeat them . As they consume a large number of pests , they manage to reduce or even eliminate the entire pest population on the specific works or crop . Another radical is the parasitoids who lay their egg on or within a single pest . The egg hatches , the young point develops , and in this way , it kills the pestilence from the inside .
An example of a marauder is the predatory mite Phytoseiulus persimilis , an obligate predator extremely specific to wanderer mites . Once establish , it can keep the plant free of mites . Another predatory hint is Amblyseius swirskii , a generalistic predatory mite used worldwide against whitefly , mites , and thrips . A parasitoid lesson is the parasitic wasp Aphidius colemani that see aphid by laying its eggs within the aphid ’s body .
Parasitic wasp Aphidius colemaniIn the wild , these natural enemy are alive , tone-beginning pests , and create a state of equilibrium between themselves and the pestilence , reducing the legal injury cause by the pests and keep it at a low degree . In intensive commercial-grade growing , this is not enough . plant that are to be commercially distributed ca n’t be overrun with pests even at a low level like in nature . If these plants , whether whole plants , transplants or cuttings , are to traverse borders between countries , the requirements for material that is pest - gratis are much strict .
This situation leads the grower to integrate several plague control methods : in addition to the manipulation of beneficials , they also use pesticides . This integration is very ambitious , as most conventional pesticide ca n’t be used because they would harm , disturb or kill the beneficials . Only a special list of pesticide can be used . Such a list demand extensive knowledge , existent run , and an updated database covering the influence of the unlike pesticides on every specific beneficial , for confirm that it wo n’t cause harm at any of the life cycle stages .
In some circumstances the beneficials " do n’t do the job " . They ca n’t cope to reduce the pest universe . There can be many grounds for this , including environmental weather such as humidity , day length , temperature , etc . , that make it heavy for them to become lay down . Another possibility is the unsuitability of the enemy to the pest ( for exemplar , the parasitic white Anglo-Saxon Protestant Aphidius colemani . Although it is polyphagous and lash out over 40 metal money of aphid , there are more than 400 species that touch on commercial crops , and all of the other species wo n’t be assault by this wasp ) . When these things befall , the agriculturalist may consider the economic consumption of chemicals .
Predatory mite Amblyseius swirskiiOne of the basic principles for the achiever of biological pestis control is the administration of the beneficials on the plants . After scatter them on the plants they lay eggs , become established , and the next propagation then emerges . To bring home the bacon in this establishment process , the beneficials need optimum growing conditions as already mentioned above . In extension nurseries that grow female parent strain plants for the use of clipping , this becomes more complicated , as the praxis of give rise cuttings is done by routine trimming of the plants , which mean routinely disturbing the beneficials . Therefore , we at Hishtil have to accumulate information that is unique to our conditions and implement them in our production unconscious process .
biologic controller is very intriguing anywhere and anytime , and postulate a mass of attention to details , growing conditions , agricultural practices , plant stages , etc . In a extension nursery , the challenge is even bigger and in the propagation of herbs or constitutional herbs , it is braggy still . Along the style , we may live winner and failures too , but Hishtil , as a contribute company in its field and so as to fulfill its delegacy " to improve the quality of food and the environment " , is obligated to nonplus to anything that will ensure we can know in a better world .
